Adjectival resultatives cross-linguistically: a morphophonological account

Not all languages that feature complex resultative constructions permit them when the resultative predicate is an AP. Well-known data from Slavic and new data from Latin attest that observation, and the following one: in both languages resultatives always feature a prefix as the resultative predicate. I suggest, then, that in these languages there is a morphological requirement such that the resultative predicate must end up affixed onto the verb, and that this prefixation mechanism cannot target adjectives, since they are always inflected for agreement. The analysis is couched within a syntactic view of argument structure and morphology.
